I recently bought a SanDisk USB flash drive, because it worked with Linux. Here’s the letter I subsequently wrote to them:

FAO Keith Norman, Regional Sales Director, UK & Ireland

Dear Mr Norman,

I recently bought a SanDisk Micro Skin 8 GB USB Flash Drive. I bought
it because it said it works with Linux and had a Linux logo on the
back. I am a Linux user and this is important to me. Having used it, I
am happy with it.

Many computer peripheral suppliers don’t seem to care about Linux, or
whether their products work with it. Sandisk appear to be different.

In future, I will seek out Sandisk products and am likely to prefer
them over your competitors.
